GEORGE H. BARKER, DE LOS ANGELES, CALIFORNIA, ASSIGNOR TO IMPROVED SANI-TARY FIXTURE COMPANY, OF LOS ANGELES, CALIFORNIA, A CORPORATION OFCALIFORNIA.

LAVATORY APPLIANCE.

To all whom it may concern.

Be it known that I, GEORGE H. BARKER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inLavatory Appliances, of which the following is a specification.

My invention relates to lavatory appliances and has particular referenceto a novel combination bath tub and wash bowl and the waste connectionsfor each thereof.

In the designing of many bat-h rooms the question of available space isan important one. It not infrequently occurs that a fullsized bath tubmay not be located within a given space and at the same time provide fora wash bowl.

One of the objects of my invention is to provide a combined bath andwash bowl in such manner as to economize in fioor space and at the sametime economize materially in the plumbing required for the installationof such fixtures.

I am aware that combined wash stands and bath tubs are not new butbelieve the waste connections for the tub and bowl, as shown in thisapplication, are new.

In plumbing ordinances it is customary to fix or limit the amount ofpipe which may be exposed to fouling on the house side of any trap. Thisresult is ordinarily accomplished by regulating the number of fixtureswithout individual traps which may be attached in series to a givenwaste pipe of stated size. A most common example of this procedure isthe installation of laundry tubs, which, under plumbing ordinances arevariously permitted to be connected with a single trap in groups of fromtwo to four.

Naturally the attempt should be made to reduce to a minimum the foulingsurface on the house side of any trap. It is apparent, however, that itis not the area of surface exposed but the amount of decomposableorganic matter which will have an opportunity to deposit upon thissurface which is significant. It is probable that many tures inbuildings are so infrequently used that the trap seals become brokenthrough evaporation. Thus a very large fouled surface may become exposedto the atmosphere of a room. Any greater use which would obviate loss ofseal through trap evaporation should be Welcome.

ing two fixtures, such as those under consideration, with a minimumlength of waste and each having a waste pipe virtually independent to apoint in close proximity to the trap, will be maintained moreeffectively in seal and will be cleaner and better scoured than if twotraps were used, one on each fixture.

An important feature of this waste pipe system is the vertical sectionof pipe, serving the lavatory, within the larger bath waste. This pipefulfils a double purpose inasmuch as it increases the scouring velocityand in addition prevents splashing and consequent undue fouling of theoverflow and waste from the bath tub itself. In other words, theseoutlet pipes from the bath will, with the stated arrangement, be just asclean in this combined fixture as in those of an independent bath tub.

lVith the waste connections as herein shown it will be seen that onetrap will serve for both fixtures and that thereby the cost ofinstallation is materially reduced.

My invention will be more readily understood by reference to theaccompanying drawings wherein Figure 1 is a side elevation of a combinedbath tub and lavatory with my novel waste connection applied thereto;Fig. 2 is an enlarged vertical section through the waste pipes shown inFig. 1. Fig. 8 is an enlarged vertical section through a modification ofthe construction shown in Figs. 1 and 2.

Referring more particularly to the drawings, it will be seen that Iprovide a bath tub 10 of any preferred construction, from the lowerportion of which extends a waste pipe 11 and near the upper end of whichis an overflow pipe 12. Mounted above the tub 10 is a lavatory 13suitably supported on the rim of the tub and provided with a waste pipe14. As shown in Fig. 2, the Waste pipe from the lavatory, the opening towhich is controlled by a stopper 15, extends downwardly into aconnection 16 being held therein by a union nut 17. Suitably secured tothe pipe 11 at a point within the connection 16 is a smaller pipeextension 18, this smaller pipe extending down and terminating at apoint considerably below the outlet 11 for the tub. The location of thepipe centrally of the larger pipe 19 provides a space therearoundthrough which water may escape from the overflow 12. The wasteconnection 11 opens into a connection 20, similar to the connection 16and this connection 20 is directly connected to a pipe 21, in which thetrap (not shown) is located.

It will be noted that the overflow from the lavatory is conducteddirectly to the: main discharge pipe 21, and has no oppor tunity to foulany of the bath connections. Furthermore, that the waste connection forthe bath is arranged to discharge almost directly into the maindischarge pipe with practically no fouling surface. An obvious advantagein this construction is in that the single trap serving the lavatory andbath has no opportunity to become broken due to evaporation, asfrequently occurs in the case of an infrequently used bath. Theconstantly used lavatory will keep the trap flushed and prevent thebreaking of the seal. In order to supply clean water to the bath thelavatory and the tub I provide a twoway bib-cock 22, one portiondischarging into the lavatory and the other into the tub. A valve 23controls the passage of the liquid into one or the other of thereceptacles. In the modified construction shown in Fig. 3, the wastepipe 14;, discharges into a double passage waste pipe, the two passagesbeing formed by a dividing web secured internally of the pipe. In Fig. 3the lavatory discharges from the pipe 14 into a pipe 24, which pipe isflattened and one-half thereof removed as at 25, the remaining portionof the pipe being bent in such manner as to form a partition 26extending downward through the pipe 27, and ,at a point past the lower T28.

I claim:

.1. The combination with a bath tub and a basin located above the tub, adrain pipe connected to the tub, and a drain for the basin consisting ofa connection imperforate with respect to the tub connections andextending from the basin down through the tub drain pipe and terminatingbelow the tub drain whereby to prevent back flow of the water from thebasin.

2. The combination, with a bathtub and a basin located above the tub, adrain and overflow pipe connected at its upper end to the upper part ofthe tub and also having a connecting branch extending to the lower partof the tub, and an imperforate drain pipe extending from the basin downthrough the first pipe and terminating at its lower end below theconnecting branch of the tub drain whereby to restrict back flow ofwater from the basin.

In testimony whereof I have hereunto signed my name in the presence oftwo sub scribing witnesses.

GEORGE H. BARKER.
